Title: Direct access storage device
Inventor: RICHIYAADO FURETSUDO HAAUTSUDO
IPC: G11B21/12
Filed: 1994-04-12
Abstract: PURPOSE: To provide a disk drive having a passive type slider showing two float heights of a float height for recording and reading operations and a 2nd height for idle state. CONSTITUTION: A disk drive 120 has a magnetic recording plane set for rotation in one direction. A converter carrier 124 can be positioned in radial direction to the magnetic recording plane and moved between a recording position and an idle position on a loop-shaped surface. On the surface of an idle zone 122, plural shallow recessed parts arranged on a loop-shaped zone are provided. These recessed parts are trenched as a whole. The direction of recessed parts depends on the carrier for converter. When turning the recessed parts laterally to the rotating direction of the magnetic recording plane, pressure under the carrier is increased and a gap is generated between a main body and the carrier or that gap is increased.  When the carrier has an air bearing plane including an area to generate the zone of relatively negative pressure, the recessed parts become a groove parallel with the rotating direction of the disk. With these recessed parts, the validity of zone of the negative pressure is decreased and the float height of the carrier is increased.

Abstract: PURPOSE:To obtain sufficient insulating properties required for inter-element isolation with excellent reproducibility by depositing an insulating film on a substrate region except an element region formed onto a compound semiconductor substrate thorugh plasma CVD and positively introducing damage due to the collisions of charged quanta to the compound semiconductor substrate. CONSTITUTION:Silicon ions are implanted selectively to a semi-insulating GaAs substrate 1 while using a resist as a mask to form element regions 3. An insulating film 4 such as a silicon oxide film, a silicon nitride film or the like is deposited on the surface of the GaAs substrate 1, and impurities are activated through heat treatment while using the insulating film 4 as a cap material. A resist mask for inter-element isolation is formed with the insulating film 4 being left as it is, and the insulating film 4 is bored selectively. The resist is removed, and an insulating film 9 such as silicon nitride is deposited while element isolation regions 5 are shaped. Accordingly, the insulating film is deposited by employing plasma CVD, thus introducing physical damage due to the collisions of SiH4 excited by a high-frequency electric field and NH3 plasma to the GaAs substrate at the initial stage of the deposition of the insulating film.

Title: Sensor amplifier circuit for pressure sensitive type touch panel
Inventor: IMADA HIROSHI
IPC: H03K17/96
Filed: 1985-04-10
Abstract: PURPOSE:To stably read the value of a sensor, by compensating the change in output voltage caused by the drift of a SC amplifier and temperature characteristic of the sensor with a feedback circuit using a microcomputer. CONSTITUTION:The output voltage of a sensor circuit 1 is digitized by an AD converter 3 through a DC amplifier 2 and inputted in a microcomputer 4 as data S. When the same value continues for (n) times as the data S, a decision means 43 decides that no input is made to a sensor. At the same time, a feedback quantity calculating means 44 calculates and outputs a feedback quantity P by regarding it as disturbance when the data S are not equal to a set value R and, when S=R, the means 44 decides that the output of the DC amplifier 2 is maintained at an appropriate value. When the data S do not become the same value continuously for (n) times, the calculating means 44 does not calculate the feedback quantity P and outputs the last calculated value, since the state has touch input to the sensor. The output is converted into an analog quantity (voltage) by means of a DA converter 5 and fed back to the DC amplifier 2 where the output is used for automatically adjusting the amplifier 2 so that the voltage at a sensor amplification output terminal 23 can become constant.

Abstract: PURPOSE:To reduce the scanning time and increase the efficiency of data transmission, by installing a slave station pause setter in correspondence to the slave station to a control device which carries out a centralized monitor to plural slave stations through a master station and then giving an interlaced scanning to a slave station in a pause mode. CONSTITUTION:The slave station pause setters SW1-SWn are installed to a remote monitor control device in correspondence to plural slave stations, and the state of these setters is added to AND gates A11-A1n which supply the output of a decoder 2. The outputs of these AND gates are applied to a rise differentiating circuit 1 via an OR gate, and the output of the circuit 1 is applied to a slave station receiving counter 3 via an OR gate 2. When the setters SW1-SWn are operated with a pause of a slave station, the counter 3 is advanced by action by the output of a final word detecting circuit 5. Then the information is not fetched from the slave station by the output of a decoder 4, but the information of the next designated station is fetched by the output of the decoder. Thus the scanning time can be reduced.

Title: Amplitude modulation receiver
Inventor: TAKEDA TADASHI
IPC: H04B1/26
Filed: 1985-04-09
Abstract: PURPOSE:To perform all wave reception by means of a single band, by setting the alteration ratio of the 1st station oscillating frequency at >=2 by using a solid-state resonator as the load of the 1st frequency converter and an equivalent solid-state resonator to an amplifier also through an LC resonance circuit. CONSTITUTION:The 1st intermediate frequency signal which is proportional to the impedance characteristic of the solid-state resonator 13 of the 1st frequency converter 1 is connected with a parallel resonance circuits of C15 and L16. An amplifier 3 feeds back to the base by means of its solid-state resonator 18 and has an amplification degree characteristic which is proportional to its impedance characteristic. The 1st intermediate frequency signal is mixed with the output of the 2nd local oscillator 5 by means of the 2nd frequency converter 4 and the 2nd intermediate frequency (Fif2) is obtained and becomes the 1/2 of the difference between the resonance frequency (fr) and antiresonance frequency (fa) of the soild-state resonator. The signal is demodulated by a detector 7 and a low frequency signal is obtained. Therefore, the high 1st intermediate frequency can be selected and image interference adjacent to the low 2nd intermediate frequency can be eliminated with the high Q-characteristic of the solid-state resonator. In addition, the spurious characteristic peculiar to the solid-state resonator can be suppressed with the LC resonance circuit.
